摘要：
The invention relates to ophthalmology, namely, to the measurement and may find practical application in the marking position of the pupil center on the plane of the rim for corrective glasses and when measuring vertex and interpupillary distances and centering of lenses.The technical result of the proposed utility model is to eliminate the trapezoidal component during marking of the pupil center on the plane of the rim and thereby decrease the error probability for centering the lenses, and the possibility of measuring the vertex and interpupillary distances to suit the individual patient anthropometric parameters and rim sizes.Device for marking the center of the pupil plane on the rim comprising a housing with a longitudinal groove on the end portion which is fixed conical tip and the sleeve-millimeter range. Graph line is formed with an oval opening in the center, is fixed on a movable rod which is located inside the longitudinal slot in the housing and the conical sleeve-tip.
